Hi expert ....I am from Singapore.My passion fruit plant has 100 over flowers everyday & there are bees and ants besides my manual pollination.Unfortunately the male flowers/anthers have no pollen grains, I took a few to dissect.My passion plant was grown from stem cutting.It was grown in pot for 1 year before I planted on ground in January 22 2023 and in June all flowers start to bloom, I have given enough potassium from burried fish heads/bodies and used coffee powder.Your advice please
